The drivetrain
The magic is in the drive train, the combination of motor and element. Variable Speed Drive technology works best with rotary screw compressors, as their flow rate and their power consumption are virtually proportional to their speed. So as the motor adapts its speed, so do the screw elements and as a result, the amount of compressed air delivered. The electric motor is specifically designed for the job, with special attention to cooling requirements and efficiency across the entire speed range.

The motor
The motors in standard VSD units are induction motors, coupled to the screw elements with gears, but our VSD+ features an interior permanent magnet motor, a revolutionary in-house design. The motor shares a rotor with the screw elements, so it’s direct-driven, exceptionally quiet and most of all, very energy-efficient. The whole drive train of the VSD+ is a closed circuit, where both motor and elements are cooled with oil, another great way to save energy.
